Congratulate
If a pilot manages to land under a canopy with a helicopter that's pierced with a sideways barb in the heart of winter you should congratulate them! People should always be congratulated for doing good things, and this is one of the best things you've ever heard of!
Can you imagine how hard landing a helicopter in just one of these horrible conditions? Congratulate them!
けい
よろこ
None
Congratulate the pilot with cake (けい)!
Cake is always the appropriate celebratory food.
